I’m very excited that these magazines are being scanned and made available by you on the Internet, I just hope you have the bandwidth to handle it 😉 (~50mb files, after all, seem to me quite massive but perhaps you live in a country with the luxury of Internet service of the absolutely most premium kind).
But there is one small problem it seems, the links that have been provided to the magazine PDFs on the website seem slightly incorrect and, for me at least, the problem seems to be that the links capitalise the first letter I in the folder Interaction: so http://www.gracenroark.net/roark/sierra/Interaction/Interaction%2001%20Fall%201991.pdf (for example) should be http://www.gracenroark.net/roark/sierra/interaction/Interaction%2001%20Fall%201991.pdf and everything works fine.
I hope you take the time to look into this, but otherwise great work, thank you for it, I hope you keep it up, and I look forward to more of these magazine issues :)!
